O.K., here's another one for you - no interesting marks, but the case is interesting. Not sure what to make of this one. The case is what caught my eye because of the slightly different writing style. I figured this was just another typical post-war medal. Once I got it, not sure what to make of it! The medal looks like it could be anywhere from late WWII to post-war, but not modern post-war. The rosette has our familiar "SU" mark on it. The case is what is interesting - yes, the style is slightly different, but on closer inspection I found that it looked different becasue it is also in a narrower column than the typical post-war case - but the most interesting part is that otherwise the case would appear to be like any other post-war case without the latch hardware - and this is the case, and it is made of Bakelite plastic - however this one is finished in black lacquer - alas, it doesn't show up well in the pictures, but it is lacquer over plastic!
I simply don't know what to make of the piece as a whole, but if I had to guess, I'd say the seller simply cobbled together a medal, a rosette, and a case - all from different periods. Nick, you seem the most familiar with aging of these Rising Suns - what do you think??
